librdkafka version (build) 0.9.1.0

this is my code

        date_default_timezone_set('PRC');
        $conf = new \RdKafka\Conf();
        $conf->set('api.version.request', 'true');
        $conf->set('ssl.ca.location', $this->kafka_setting['ca_file']);
        $conf->set('message.send.max.retries', 5);
        $conf->set('security.protocol', 'SASL_SSL');
        $conf->set('sasl.mechanisms', 'PLAIN');
        $conf->set('sasl.username', $this->kafka_setting['sasl_plain_username']);
        $conf->set('sasl.password', $this->kafka_setting['sasl_plain_password']);

        $rk = new \RdKafka\Producer($conf);
        $rk->setLogLevel(LOG_DEBUG);
        $rk->addBrokers($this->kafka_setting['bootstrap_servers']);

        $topic_conf = new  \RdKafka\TopicConf();

        $topic = $rk->newTopic($this->kafka_setting['topic_name'],$topic_conf);
        $a = $topic->produce(RD_KAFKA_PARTITION_UA, 0, "Message hello kafka");
        $rk->poll(0);
        while ($rk->getOutQLen() > 0) {
            $rk->poll(50);
        }
        echo "send succ" . PHP_EOL;
